' FonjeHy-of seid nozzie ilere is dispose Ve burner jet 29, with the orice thereof ooncentricaliy disposed with Said piping and faced over a. sleeve 30, tted Vwith. said piping. ile position against the sieeve the elbow l by the cap 31, screw threaded to the externally threaded piping 20.

Extending from the elbow 13 there is provided the ilange 32 yhaving a central opening 33 in alignment with the opening of the elbow extending in the upper branch thereof.

T he fiange 32 is counter bored at 34, into which there is fitted the stufliug box 35, the latter being mounted inposition by the stud bolts 36 and the nuts 37. Disposed through the stutling box there is extended the rod 38, which at thenozzleend is provided with a needle point or tip 39, adapted to cooperate with the jet orifice 29 to limit the flow of liquid therethrough. A helical or worm fitting 29, mounted upon the rod within the sleeve 30, serves to center the rod and at the same time impart a whirling movement to the liquid flowing through the jet.

The portion of the rod 38 extending outwardly from the stuiling box is provided with packing 40, such as of asbestos, which is {irml forced in engagement to seal the rod by tlie strap 41, including a gland extension 42, and held in position on the flange 32 by the bolts 43.'

Mounted upon the stud bolts 36 there is disposed a holder or anchoring plate 44, which is oriiced at 45 and 46 to r the bolts 36. Outer nuts 47 and inner jamb nuts 48 irmly anchor the holder or plate 44 in position.

rlhe free end 49 of the rod 38 is threaded and this is passed through a central threaded orifice 50 in the holder or plate 44.

Adjustment of the needle point or tip 39, relatively to the jet 29, may be made by rotating the rod the. threaded engagement in the orlfice 50 of the plate 44, serving to give the setting to get a spray of predetermined ,characteristics which, with the material such as molten sulfur, fuel oil, liquid material or other combustible material, will give maximum eiciency.

This setting is then fixedl by the lock nuts 51 and 52 on said rod at the end 49, which lock nuts are disposed to either side of the holder or plate 44.

It will beobserved that the holder 44 as mounted upon the bolts 36 and to which the free end 49 of the rod 38 is fixed, is suiiiciently spaced from the stulling box mounting to allow substantial movement of this assembly. Should the tip 29 become clogged for any reason,for purposesA of cleansing the same the inner )amb nuts 48 are loosened for a suflicient distance and then the plate or holder 44 is sharply driven forward to force the point or tip 39 upon the jet 29. This serves to clean or punch out of the orifice any material tending to stop it up or clog it, without the necessity of further dismantling of the apparatus, and the original adjustment is regained by merely again tightening the plate 44 in position by means of )amb nuts 48.

eely Islide upon Furthermore, it will be observed that should it become necessary to remove or replace the worm or helical fitting 29', the rod 38 may be withdrawn through the flange 32 yby bodily removing the stu ng box35, by

releasing the bolts 36 holding' the same in osition. The stuflin box assembl carrying the rod 38 may t en be sli pej out to cleanse or replace the helica or worm fitting 29-.

It will vthus be observed that I have provided an efficient spray burner which may be eiicien'tl used in connection with combustible materia s, the material so used being capable of being maintained l'uid, as in the case of sulfur, or, for purposes of increasin the fluidity of viscous materials, suchas eavy fuel oils by providing a burner and `feed line thoroughly ]acketed for heating the same. Also, it will be observed that I may utilize the jacketed spaces so provided for purposes of heat insulating as well as heating where a previously heated material is fed through the pipe line.

It willV also be observed that I have provided a spray burner capable of extreme refinement of adjustment or setting, which adjustment need not be lost should the burner become clogged due to any obstruction and, furthermore, have provided means for readily cleansing the jet and returning the needle adjustment to the original settmg, which will give the predetermined maximum eliciency of combustion or spray.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent, is-
